Anyone have any ideas as how to juice 50 extra HP on the cheap out of a 530xi, or would it ruin xDrive and not be worth having AWD in the end?

On the cheap? No way at all.

Although, if, to you, cheap means "anything less than $20,000", then it could probably be done with some cams, S/W, intake/header/exhaust, maybe a supercharger that doesn't exist for the market yet.

Sell your 530XI for top dollar and get a 535XI and chip it.
